How do I use environment variables in AWS SAM?

How do I use environment variables in AWS SAM?

You can define environment variables in your AWS SAM template under the Environment property of your function.

Can you show me an example of how to set them up?

Sure! Here's a snippet:

Resources:
  MyFunction:
    Type: AWS::Serverless::Function
    Properties:
      Handler: app.handler
      Environment:
        MY_VARIABLE: 'value'

What if I want to use secrets instead of plain text?

You can use AWS Secrets Manager or Parameter Store to manage sensitive information securely.

How do I reference those secrets in my SAM template?

You can reference them using the Fn::Sub or Ref functions in your environment variables.
